I have the same issue with my riing quad 12 fans. i bought 9 ring quad 12 fans and 2 riing 20 200mm fans. i spent over 700 dollars on these fans. as soon as i downloaded the thermal take software. the center ring on 4 of the fans shut off and will not come back on . i changed the controller unplugged the controller from the usb 2.0 port. i even reset my pc nothing worked to restore the center rings. i contacted thermal take they made up an excuse that the software is beta. now i had uninstall the software bc no controller warning keeps popping up. thermal take doesn't care they just want money. they sell nice expensive fans that do not work and they knowingly do this . i saw a youtube video posted by thermal take promoting the ring quad fans and in the video u can see the same no controller warning pop up. so they sell the fans knowing the the person buying will not be able to use them . THAT'S BAD BUSINESS THERMALTAKE !!!!!!!!!!!!!!!!!!!!!!
